1308 ETN9 Bearing Product Overview & Core Advantages
The 1308 ETN9 is a double row angular contact ball bearing engineered for exceptional performance in demanding applications. As a metric bearing with an open design, it is optimized to handle significant combined loads, including radial and bidirectional axial forces. Its compact bearing dimensions (40 mm bore, 90 mm OD, 23 mm width) and robust construction deliver high rigidity and operational stability, making it an ideal choice for high-precision machinery requiring reliable, long-lasting performance.
1308 ETN9 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 1308 | Standard bearing series designation, defining the core dimensions (40mm bore, 90mm OD). |
| E | Indicates an optimized internal design for increased load capacity. |
| TN9 | Specifies a glass fiber reinforced polyamide (Nylon) cage. This design is lightweight and promotes lower friction, contributing to high-speed performance and smooth operation. |
1308 ETN9 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row ball complement and optimized internal geometry (E-design) provide superior high rigidity, enabling the bearing to support substantial radial dynamic load ratings of 7605 lbf and radial static load ratings of 2520 lbf, effectively managing combined loads.
- High-Speed Performance: The lightweight TN9 nylon cage reduces centrifugal forces and ensures stable operation, allowing for a high limiting speed of 9,500 rpm.
- Precision & Durability: Manufactured from chrome steel for both rings and balls, this precision bearing offers high wear resistance and dimensional stability. The open seal type allows for custom lubrication strategies to suit specific operational needs.
- Operational Reliability: The bearing comes lubricated and operates effectively within a temperature range of -30°C to 110°C, ensuring consistent performance in various industrial environments.
